The information provided
on this page is calculated
data based on driving both
channels to rated output.
Other parameters used in
calculation include a con-
servative idle draw esti-
mate of 90 Watts and a
conservative estimation of
efficiency at 85%. Informa-
tion is provided for the pur-
pose of getting an idea of
current draw and heat pro-
duced. Actual perfor-
mance will vary depending
on environment, program
material, load, signal, and
AC mains voltage and fre-
quency. Figures calcu-
lated for various program
material use estimated
duty cycles, taking into
account the typical crest
factor for each type of
source material. Values of
calculated current draw
are intended to represent
average draw correspond-
ing to the thermal breaker
requirements that should
be met to handle the am-
plifier as a load on the AC
mains. Peak current draw
with dynamic program ma-
terial may be significantly
higher. Thermal informa-
tion is provided to assist
with calculating air condi-
tioning needs. The above
data should not be con-
strued as specifications.
